iSHARES® INFLATION HEDGED HIGH YIELD BOND ETF

Ticker: HYGIStock Exchange: NYSE Arca

Investment Objective

The iShares Inflation Hedged High Yield Bond ETF (the “Fund”) seeks to track the investment results of an index designed to mitigate the inflation risk of a portfolio composed of U.S. dollar-denominated, high yield corporate bonds.

Fees and Expenses

The following table describes the fees and expenses that you will incur if you buy, hold and sell shares of the Fund. The investment advisory agreement between iShares U.S. ETF Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except: (i) the management fees, (ii) interest expenses, (iii) taxes, (iv) expenses incurred with respect to the acquisition and disposition of portfolio securities and the execution of portfolio transactions, including brokerage commissions, (v) distribution fees or expenses, and (vi) litigation expenses and extraordinary expenses. The Fund may incur “Acquired Fund Fees and Expenses.” Acquired Fund Fees and Expenses reflect the Fund's pro rata share of the fees and expenses incurred indirectly by the Fund as a result of investing in other investment companies. The impact of Acquired Fund Fees and Expenses is included in the Fund's total return but is not included in the Fund's ratio of expenses to average net assets. Both figures are shown in the Financial Highlights section of the Fund's prospectus (the “Prospectus”). BFA, the investment adviser to the Fund, has contractually agreed to waive a portion of its management fees so that the Fund’s total annual fund operating expenses after the fee waiver are equal to the Acquired Fund Fees and Expenses attributable to the Fund’s investment in the iShares iBoxx $ High Yield Corporate Bond ETF (“HYG” or the “Underlying Fund”), after taking into account any fee waivers by HYG, plus 0.05% through February 29, 2028. The contractual waiver may be terminated prior to February 29, 2028 only upon written agreement of the Trust and BFA.

You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below.

 

Annual Fund Operating Expenses (ongoing expenses that you pay each year as a percentage of the value of your investments)1
Management Fees	Distribution and Service (12b-1) Fees	Other Expenses	Acquired Fund Fees and Expenses	Total Annual Fund Operating Expenses	Fee Waiver and/or Expense Reimbursement	Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement
0.55%	None	0.00%	0.47%	1.02%	(0.50)%	0.52%

1Operating expenses paid by BFA under the Investment Advisory Agreement exclude Acquired Fund Fees and Expenses, if any.

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

 

1 Year	3 Years	5 Years	10 Years
$53	$167	$409	$1,103

S-1

Portfolio Turnover. The Fund or the Underlying Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate for the Fund or the Underlying Fund may indicate higher transaction costs and may cause the Fund or the Underlying Fund to incur increased expenses. These costs, which are not reflected in the Annual Fund Operating Expenses or in the Example (except costs to the Underlying Fund included as part of Acquired Fund Fees and Expenses), affect the Fund’s performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 0% of the average value of its portfolio. To the extent the Underlying Fund incurs costs from high portfolio turnover, such costs may have a negative effect on the performance of the Fund.

Principal Investment Strategies

The Fund seeks to track the investment results of the BlackRock Inflation Hedged High Yield Bond Index (the “Underlying Index”). The Underlying Index is designed to minimize the inflation risk of a portfolio composed of U.S. dollar-denominated, high yield corporate bonds, which is represented in the Underlying Index by the Underlying Fund, by including a series of up to 10 inflation swap contracts with different maturities (as determined by BlackRock Index Services, LLC (the “Index Provider”)). As of October 31, 2024, the Underlying Index includes approximately 11 components (including shares of the Underlying Fund), as well as a cash position that is intended to reflect the collateral that must be held to manage the swaps positions.

The Fund uses its investment in the Underlying Fund primarily to gain exposure to U.S. dollar-denominated, high yield corporate bonds (commonly referred to as “junk bonds”). The Fund seeks to track the inflation hedging component of the Underlying Index primarily through the use of positions in inflation swaps (i.e., derivative contracts used to transfer inflation exposure by exchanging a fixed cash flow for a floating cash flow). The Fund makes fixed-rate payments based on a notional reference amount while receiving floating-rate payments on the same notional reference amount determined from an inflation index. The different maturities and weights of the swap contracts included in the Underlying Index are intended to hedge the portfolio’s inflation exposure at key points on the yield curve, as determined by the Index Provider. The Underlying Index includes a fixed number of shares (to be adjusted in the event of any stock splits) of the Underlying Fund, and the Index Provider rebalances the weights of the swap contracts included in the Underlying Index daily. On a monthly basis, the Index Provider will add new swap contracts to the Underlying Index and remove the previous month’s swap contracts.

The Fund seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in component securities and instruments in the Fund’s Underlying Index. Cash and cash equivalent investments associated with a derivative position will be treated as part of that position for the purposes of calculating the percentage of investments included in the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

The Fund may also invest in other instruments designed to transfer inflation exposure from one party to another, including

but not limited to U.S. Treasury Inflation Protected Securities (“TIPS”), total return swaps, futures and options (collectively with inflation swaps, “inflation hedging instruments”). The Fund’s investments in inflation hedging instruments are not intended to mitigate credit risk or other factors influencing the price of U.S. dollar-denominated, high yield corporate bonds, which may have a greater impact than inflation rates. Moreover, to the extent that inflation exposure has been priced into the U.S. dollar-denominated, high yield corporate bonds owned by the Underlying Fund, the Fund will underperform the Underlying Fund even during inflationary periods.

The Commodity Futures Trading Commission (“CFTC”) has adopted certain requirements that subject a registered investment company and its adviser to regulation by the CFTC if the registered investment company invests more than a prescribed level of its net asset value in CFTC-regulated futures, options and swaps, or if the registered investment company markets itself as providing investment exposure to such instruments. Due to the Fund’s potential use of such instruments above the prescribed levels, it is considered a “commodity pool”under the Commodity Exchange Act (“CEA”). BFA is considered a commodity pool operator (“CPO”) with respect to the Fund and is subject to regulation by the CFTC and the National Futures Association (“NFA”).

BFA uses an indexing approach to try to achieve the Fund’s investment objective. The Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by aiming to keep portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund and the Underlying Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities and/or other instruments that collectively have an investment profile similar to that of an applicable underlying index. The securities and/or other instruments selected are expected to have, in the aggregate, investment characteristics (based on factors such as market value and industry weightings), fundamental characteristics (such as return variability, duration (i.e., a security's price sensitivity to a change in interest rates), maturity or credit ratings and yield) and liquidity measures similar to those of an applicable underlying index. The Fund or the Underlying Fund may or may not hold all of the securities and/or other instruments in the applicable Underlying Index.

The Fund may lend securities from its portfolio representing up to one-third of the value of the Fund's total assets (including the value of the collateral received).

The Underlying Index is sponsored by the Index Provider,  an affiliated person of the Fund and of BFA, the Fund’s investment adviser. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and

S-2

publishes information regarding the market value of the Underlying Index.

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. The Fund is subject to certain risks, including the principal risks noted below, any of which may adversely affect the Fund's net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective. Certain key risks are prioritized below (with others following in alphabetical order), but the relative significance of any risk is difficult to predict and may change over time. You should review each risk factor carefully.

High Yield Securities Risk. Securities that are rated below investment-grade (commonly referred to as “junk bonds,” which may include those bonds rated below “BBB-” by S&P Global Ratings and Fitch Ratings, Inc. (“Fitch”) or below “Baa3” by Moody's Investors Service, Inc. (“Moody's”)), or are unrated, may be deemed speculative, may involve greater levels of risk than higher-rated securities of similar maturity and may be more likely to default.

Inflation-Linked Instruments Risk. There can be no assurance that the Consumer Price Index (“CPI”), which typically is referenced by inflation swaps, or any other inflation index will accurately measure the rate of inflation experienced in the U.S. or the rate of expected future inflation reflected in the prices and yields of bonds held by the Fund. CPI swaps may cause the Fund’s NAV and returns to be more volatile and expose the Fund to counterparty risk. The Fund could lose money on both the inflation hedging instruments and the high yield corporate bonds, and the present value of the Fund’s portfolio investments could decrease if inflation increases.

Hedging Risk. The Fund’s use of inflation hedging instruments is intended solely to mitigate the impact of inflation on the performance of bonds in its portfolio. The hedging strategy is not intended to mitigate credit risk, interest rate risk, or other factors, which may have a greater impact than inflation on the bonds’ returns. There is no guarantee that hedging will completely eliminate the impact of inflation on the Fund’s bond portfolio. In addition, if interest rates exceed the inflation rate, the Fund’s investments will generally underperform a portfolio composed solely of the bonds. In certain low inflation environments, the hedging strategy could result in disproportionately larger losses in the hedging positions as compared to gains in the bond positions attributable to interest rate changes. The Fund seeks to hedge only the impact of inflation and, as a result, if floating interest rates exceed inflation-linked rates, the Fund will not be hedged. There is no guarantee that the Fund will have positive returns, even in times of sharply rising inflation, during which the Fund’s

hedging might be expected to mitigate the effects of inflation. The Fund incurs expenses when entering into hedging positions. Moreover, to the extent that inflation risk has been priced into bonds held by the Fund or the Underlying Fund, the Fund will underperform the Underlying Fund even during inflationary periods.

Investment in Underlying Fund Risk. The Fund invests in the Underlying Fund, so the Fund’s investment performance and risks are likely to be directly related to those of the Underlying Fund. The Fund’s NAV will change with changes in the value of the Underlying Fund and other assets that the Fund holds. The shares of the Underlying Fund may trade at a premium or discount to the Underlying Fund’s NAV. Investors in the Fund will indirectly bear the expenses charged by the Underlying Fund, and an investment in the Fund may entail more expenses than a direct investment in the Underlying Fund.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns. Local, regional or global events such as war, acts of terrorism, pandemics or other public health issues, recessions, the prospect or occurrence of a sovereign default or other financial crisis, or other events could have a significant impact on the Fund and its investments and could result in increased premiums or discounts to the Fund’s NAV.

Index-Related Risk. The Index Provider may rely on various sources of information to assess the criteria of components of the Underlying Index, including information that may be based on assumptions and estimates. Neither the Fund nor BFA can offer assurances that the Index Provider’s methodology or sources of information will provide an accurate assessment of included components or will result in the Fund meeting its investment objective. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur, and the Index Provider may not identify or correct them promptly or at all, which may have an adverse impact on the Fund and its shareholders. Because the Index Provider is relatively new to the creation of indexes, these risks may be greater with respect to the Underlying Index than in the case of an index maintained by a long-standing index provider. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the Index Provider or a third-party data provider and could cause the Index Provider to postpone a scheduled rebalance. This could cause the Underlying Index to vary from its normal or expected composition.

Asset Class Risk. The securities and other assets in the Underlying Index or in the Fund’s portfolio may underperform in comparison to financial markets generally, a particular financial market, another index, or other asset classes.

Assets Under Management (AUM) Risk. From time to time, an Authorized Participant (as defined below in Authorized Participant Concentration Risk), a third-party investor, the Fund’s adviser, an affiliate of the Fund’s adviser, or another fund may invest in the Fund and hold its investment for a specific period of time to allow the Fund to achieve size or scale. There can be no assurance that any such entity would not redeem its investment or that the size

S-3

of the Fund would be maintained at such levels, which could negatively impact the Fund.

Authorized Participant Concentration Risk.  An “Authorized Participant” is a member or participant of a clearing agency registered with the SEC, which has a written agreement with the Fund or one of its service providers that allows the Authorized Participant to place orders for the purchase and redemption of creation units (“Creation Units”). Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. There are a limited number of institutions that may act as Authorized Participants for the Fund, including on an agency basis on behalf of other market participants. No Authorized Participant is obligated to engage in creation or redemption transactions. To the extent that Authorized Participants exit the business or do not place creation or redemption orders for the Fund and no other Authorized Participant places orders, Fund shares are more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting.

Call Risk. During periods of falling interest rates, an issuer of a callable bond held by the Fund or the Underlying Fund may “call”or repay the security before its stated maturity, and the Fund or the Underlying Fund may have to reinvest the proceeds in securities with lower yields, which would result in a decline in the Fund's or Underlying Fund's income, or in securities with greater risks or with other less favorable features.

Commodity Regulatory Risk. The regulatory requirements governing the use of commodity futures, options on commodity futures, certain swaps or certain other investments could change at any time.

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in the securities or other assets of one or more issuers, countries or other geographic units, markets, industries, project types, or asset classes.

Credit Risk. Debt issuers and other counterparties may be unable or unwilling to make timely interest and/or principal payments when due or otherwise honor their obligations. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also adversely affect the value of the Fund’s or Underlying Fund's investment in that issuer. The degree of credit risk depends on an issuer's or counterparty's financial condition and on the terms of an obligation.

Cybersecurity Risk. Failures or breaches of the electronic systems of the Fund, its adviser, distributor, Index Provider, other service providers, counterparties, or issuers of assets in which the Fund invests may cause disruptions that negatively impact the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. The Fund cannot control the cybersecurity plans and systems of its service providers, counterparties, and other third parties whose activities affect the Fund. In addition, cyber incidents may adversely impact the issuers of securities in which the Fund invests, which may cause such investments to lose value.

Income Risk. The Fund’s income may decline if interest rates fall. This decline in income can occur because the Fund may subsequently invest in lower-yielding bonds as bonds in its portfolio mature, are near maturity or are called, as bonds in the Underlying Index are substituted, or if the Fund otherwise needs to purchase additional bonds.

Industrial Companies Risk. Industrial companies face a number of risks, including supply chain and distribution disruptions, business interruptions, product obsolescence, third-party vendor risks, cyber attacks, trade disputes, product recalls, liability claims, scarcity of materials or parts, excess capacity, changes in consumer preferences, and volatility in commodity prices and currencies. The performance of such companies may also be affected by technological developments, labor relations, legislative and regulatory changes, government spending policies, and changes in domestic and international economies.

Inflation Risk. The Fund seeks to mitigate many of the adverse impacts of inflation primarily through the use of swaps linked to the CPI. The CPI is a measure that examines the weighted average of prices of a basket of consumer goods and services, and measures changes in the purchasing power of the U.S. dollar and the rate of inflation. CPI swaps will not mitigate inflation risk regarding distributions made by the Fund itself.

By entering into a CPI swap, the Fund effectively turns the inflation component of the bonds held by the Fund or the Underlying Fund from fixed rates into floating rates. The Fund will lose money on the CPI swap and underperform the Underlying Index if inflation is lower than the expected rate being hedged. The Fund will benefit from a CPI swap if actual inflation (as measured by the CPI) during the time period in which the Fund holds the swap is the same or greater than the level of inflation expected for that period.

Interest Rate Risk. Interest rate risk refers to the risk of fluctuations in the value of a fixed-income security due to changes in the general level of interest rates. Interest rate changes can be sudden and unpredictable and are influenced by a number of factors, including government policy, monetary policy, inflation expectations, perceptions of risk, and supply and demand for fixed-income securities. An increase in interest rates generally will cause the value of fixed-income securities to decline. Securities with longer maturities generally are more sensitive to interest rate changes and subject to greater fluctuations in value. Changes in interest rates may have unpredictable effects on fixed-income markets and result in heightened volatility and lower liquidity for certain instruments, which may adversely affect a Fund’s performance. During periods of very low or negative interest rates, a Fund may be unable to maintain positive returns or pay dividends to shareholders.

Issuer Risk. The performance of the Fund depends on the performance of individual securities or other assets to which the Fund has exposure. The value of securities or other assets may decline, or perform differently from the market as a whole, due to changes in the financial condition or credit rating of the issuer or counterparty.

Management Risk. The Fund generally does not attempt to take defensive positions under any market conditions, including declining markets. As the Fund will not fully replicate the

S-4

Underlying Index and may hold securities or other assets not included in the Underlying Index, it is subject to the risk that the investment strategy of BFA may not produce the intended results. There is no guarantee that the Fund’s investment results will have a high degree of correlation to those of the Underlying Index or that the Fund will achieve its investment objective.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares (including through a trading halt), losses from trading in secondary markets, hedging losses, periods of high volatility, and disruptions in the process of creating and redeeming Fund shares. Any of these factors, among others, may lead to the Fund’s shares trading in the secondary market at a premium or discount to NAV or to the intraday value of the Fund’s portfolio holdings. If you buy Fund shares at a time when the market price is at a premium to NAV or sell Fund shares at a time when the market price is at a discount to NAV, you may pay significantly more or receive significantly less than the underlying value of the Fund shares.

Non-Diversification Risk. The Fund is classified as “non-diversified.” This means that, compared with funds that are classified as “diversified,” the Fund may invest a greater percentage of its assets in securities or other instruments representing a small number of issuers or counterparties and thus may be more susceptible to the risks associated with these particular issuers or counterparties. As a result, the Fund's performance may depend to a greater extent on the performance of a small number of issuers or counterparties, which may lead to more volatility in the Fund’s NAV.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third parties, failed or inadequate processes and technology or systems failures. The Fund and BFA seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

Prepayment Risk. During periods of falling interest rates, issuers of certain debt obligations may repay principal prior to the security’s maturity, which may cause the Fund or the Underlying Fund to have to reinvest in securities with lower yields or higher risk of default, resulting in a decline in the Fund’s income or return potential.

Privately Issued Securities Risk. Privately issued securities are securities that have not been registered under the Securities Act of 1933, as amended (the “1933 Act”). Such securities typically are subject to legal restrictions on resale and generally are not traded in established public markets. As a result, privately issued securities may be deemed to be illiquid investments, may be more difficult to value than publicly traded securities, may be subject to wide fluctuations in value and may have higher transaction costs. There can be no assurance that a trading market will exist at any time for any particular privately issued security. Difficulty in selling such securities at a desirable time or price may result in a loss to the Fund.

Risk of Investing in the U.S. Investing in U.S. issuers subjects the Fund to legal, regulatory, political, currency, security, and

economic risks that are specific to the U.S. Certain changes in the U.S., such as a weakening of the U.S. economy or a decline in its financial markets, may have an adverse effect on U.S. issuers.

Risk of Swap Agreements. A swap is a two-party contract that generally obligates each counterparty to exchange periodic payments based on a pre-determined underlying investment or notional amount and to exchange collateral to secure the obligations of each counterparty. Swaps may be leveraged and are subject to counterparty risk, credit risk and pricing risk. Swaps may be subject to illiquidity risk, and it may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Small Fund Risk. When the Fund’s size is small, the Fund may experience low trading volume and wide bid/ask spreads. In addition, the Fund may face the risk of being delisted if it does not meet certain requirements set by the listing exchange. Any resulting liquidation of the Fund could lead to elevated transaction costs for the Fund and negative tax consequences for its shareholders.

Tax Risk. The Fund invests in derivatives. The federal income tax treatment of a derivative may not be as favorable as a direct investment in an underlying asset.  Derivatives may produce taxable income and taxable realized gain. Derivatives may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund’s distributions may be treated as ordinary income rather than as capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”). If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund. Income from swaps is generally taxable. In addition, the tax treatment of certain derivatives, such as swaps, is unsettled and may be subject to future legislation, regulation or administrative pronouncements issued by the U.S. Internal Revenue Service (“IRS”). Because the Fund invests in the Underlying Fund, the Fund’s realized losses on sales of shares of the Underlying Fund may be indefinitely or permanently deferred as “wash sales.”Distributions of short-term capital gains by the Underlying Fund will be recognized as ordinary income by the Fund and would not be offset by the Fund’s capital loss carryforwards, if any. Capital loss carryforwards of the Underlying Fund, if any, would not offset net capital gains of the Fund. Each of these effects is caused by the Fund’s investment in the Underlying Fund and may result in distributions to Fund shareholders being of higher magnitude and less likely to qualify for lower capital gain tax rates than if the Fund were to invest directly in the securities and other instruments composing its portfolio.

Tracking Error Risk. The Fund may be subject to “tracking error,”which is the divergence of the Fund’s performance from that of

S-5

the Underlying Index. Tracking error may occur due to a number of factors, including differences between the securities and other assets held in the Fund’s portfolio and those included in the Underlying Index; differences in the timing and methodologies used to value securities and other assets; transaction costs and other expenses incurred by the Fund that the Underlying Index does not incur; the Fund’s holding of uninvested cash; differences in the timing of the accrual or the valuation of dividends or interest received by the Fund or distributions paid to Fund shareholders; tax gains or losses; the requirements for the Fund to maintain pass-through tax treatment; portfolio transactions carried out to minimize the distribution of capital gains to shareholders; the acceptance of custom baskets; changes to the Underlying Index; and impacts to the Fund of complying with certain regulatory requirements or limits. Tracking error risk may be heightened during times of increased market volatility or other unusual market conditions. To the extent that the Fund seeks to achieve its investment objective through investments in the Underlying Fund, the Fund may experience increased tracking error as compared to investing directly in the securities or other assets included in the underlying index of the Underlying Fund. A Fund that tracks an index with exposure to swaps, options, futures and/or other derivatives may experience higher tracking

error than ETFs that do not track such indexes. Until the Fund reaches greater scale, it may experience higher tracking error than is typical for similar index ETFs.

Valuation Risk. The price that the Fund could receive upon the sale (or other disposition) of a security or other asset may differ from the Fund’s valuation of the security or other asset, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology. The price received by the Fund also may differ from the value used by the Underlying Index. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when investors are not able to purchase or sell Fund shares. Authorized Participants that create or redeem Fund shares on days when the Fund is holding fair-valued securities or other assets may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the securities or other assets not been fair valued or been valued using a different methodology. The ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Performance Information

The performance information below illustrates how the Fund’s performance has varied over different periods and provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund has varied from one calendar year to another over the periods shown. The table compares the Fund’s performance to that of an appropriate broad-based securities market index and the Underlying Index. Fund returns assume the reinvestment of any dividends and distributions. The Fund’s returns reflect the impact of any agreements to waive or reimburse expenses, which would reduce performance if not in effect. Past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future. Updated performance information, including the Fund’s current NAV, may be obtained by visiting www.iShares.com or by calling 1-800-iShares (1-800-474-2737) (toll free).

After-tax returns in the table above are calculated using the historical highest individual U.S. federal marginal income tax rates and do not reflect the impact of state or local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to tax-exempt investors or investors who hold shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). Fund returns after taxes on distributions and sales of Fund shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sales of Fund shares. As a result, Fund returns after taxes on distributions and sales of Fund shares may exceed Fund returns before taxes and/or returns after taxes on distributions.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. James Mauro and Karen Uyehara (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Mauro and Ms. Uyehara have been Portfolio Managers of the Fund since 2022.

Purchase and Sale of Fund Shares

The Fund is an ETF. Individual shares of the Fund may only be bought and sold in the secondary market through a broker-dealer. Because ETF shares trade at market prices rather than at NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the Fund (bid) and the lowest price a seller is willing to accept for shares of the Fund (ask) when buying or selling shares in the secondary market (the “bid-ask spread”).

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an IRA, in which case, your distributions generally will be taxed when withdrawn.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.
